A water jet , Laser Cutting with Pipe Cutting,CNC Bending is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. The term abrasivejet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.  Waterjet is a generic term used to describe equipment that uses a high pressure stream of water for cutting or cleaning purposes. Abrasivejet is a subcategory of waterjet in which abrasive is introduced to accelerate the process. Pure waterjet and water-only cutting are phrases for specifically distinguishing waterjets that do not use abrasive. In other words: abrasivejet and pure waterjet are kinds of waterjet, and waterjet is a kind of machinery.  It is normal, and common, to use the term waterjet to refer to abrasivejets, though in some cases it can be confusing. On this web site, we’ll use waterjet when referring to topics that cover both pure waterjets and abrasivejets, and use the terms pure waterjet and abrasivejet when discussing topics that are specific to one or the other.
